We propose a multiagent, large-scale, vehicle routing modeling framework for the simulation of transportation system. The goal of this paper is twofold. Firstly, we investigate how individual and social knowledge interact and ultimately influence the effectiveness of resulting traffic flow. Secondly, we evaluate how different discrete-event simulation designs (delays vs. queuing) affect conclusions within the model. We present a new agent-based model that combines the efficient discrete-event approach to modeling with the intelligent drivers who are capable to learn about their environment in the long-term perspective from both, individual experience, and widely available social knowledge. The approach is illustrated as practical application to modeling commuter behavior in the city of Winnipeg, Manitoba, Canada. All simulations in the paper are fully reproducible as they have been carried out by utilizing a set of opensource libraries and tools that we have developed for the Julia programming language and that are openly available on GitHub.

Harvesting shallow geothermal energy for heating and cooling building spaces in winter and summer is considered environmentally friendly and renewable. Recently, geothermal energy piles have been used as heat exchanger elements in ground source heat pump systems to exchange heat with the ground underneath buildings for heating and cooling purposes. However, imposing thermal cycles on such piles may result in possible adverse effects on their structural and geotechnical performance. A comprehensive understanding of the behavior of geothermal energy piles is therefore vital for the successful applications of such systems. This paper aims to investigate the interaction between the soil and geothermal energy pile subjected to a combination of mechanical loading and thermal cycles. Coupled thermo-hydro-mechanical (THM) finite element analyses were carried out on a hypothetical geothermal energy pile using climatic and geological conditions in Winnipeg, Manitoba, Canada. Numerical results were presented in this paper in terms of pile head displacements, strains, and stresses developed in the pile, as well as shaft friction and effective radial stresses along the pile-soil interface. The effects of heating and cooling on the ultimate geotechnical pile capacity were also presented. Based on the numerical results, it was found that the thermo-mechanical loads have considerable effects on the geothermal energy pile responses. [ABSTRACT FROM AUTHOR]

Ethical research practice within community-based research involves many dimensions, including a commitment to return results to participants in a timely and accessible fashion. Often, current Indigenous community-based research is driven by a partnership model; however, dissemination of findings may not always follow this approach. As a result, products may not be as useful to participants who were motivated to be involved in the research process. We conducted a seven-week workshop on three occasions with different First Nations and Metis women and girls (age 8-12) in Winnipeg, Manitoba. The workshop explored participants' perspectives around health, safety, and family wellbeing using a strength-based, participatory approach. Participants noted that a key challenge they face when interacting with researchers, policy makers, and program staff is the lack of tailored dissemination materials. Returning results in a format that meets the expressed desire of participants is an ethical necessity to ensure that research is not perpetuating past colonial practices. Doing so quickly and with meaningful content requires careful execution and consideration, especially when working within intergenerational contexts. We describe in this paper how results were returned to families in an accessible way outlining the role that integrated knowledge exchange can play in the process of healing. [ABSTRACT FROM AUTHOR]

Background: Invasive pneumococcal disease (IPD, Streptococcus pneumoniae) has been a nationally notifiable disease in Canada since 2000. The use of conjugate vaccines has caused a shift in the distribution of serotypes over time. This report is a summary of the demographics, serotypes and antimicrobial resistance of IPD isolates collected in Canada in 2021 and 2022. Methods: The National Microbiology Laboratory (NML) of the Public Health Agency of Canada in Winnipeg, Manitoba collaborates with provincial and territorial public health laboratories to conduct national surveillance of IPD. There were 1,999 isolates reported in 2021 and 3,775 isolates in 2022. Serotype was determined by the Quellung reaction or whole-genome sequencing (WGS). Antimicrobial susceptibilities were determined by WGS methods, broth microdilution, or data shared by collaborators in the Canadian Antimicrobial Resistance Alliance program at the University of Manitoba. Population-based IPD incidence rates were obtained through the Canadian Notifiable Disease Surveillance System. Results: The incidence of IPD in Canada was 5.62 cases per 100,000 population in 2021, decreasing from the peak of 10.86 cases per 100,000 population in 2018. Serotypes with increasing trends (p<0.05) between 2018 and 2022 included: 4 (6.1%–12.4%), 9V (1.0%–5.1%) and 12F (4.8%–5.4%). The overall prevalence of PCV13 serotypes increased over the same period (31.2%−41.5%, p<0.05) while the prevalence of non-vaccine types decreased significantly (27.3%–21.5%, p<0.0001). The highest rates of antimicrobial resistance in 2021 and 2022 were seen with clarithromycin (21%, 2021; 24%, 2022) and erythromycin (22%, 2021; 24%, 2022). Multidrug-resistant IPD continued to increase from 2018 to 2022 (6.7%–12.6%, p<0.05). Conclusion: The number of cases of IPD continued to decrease in 2021 in comparison to previous years, however, 2022 saw a return to pre-COVID-19 levels. Disease due to PCV13 serotypes 3, 4, 9V and 19F, as well as non-PCV13 serotypes 12F and 20, is increasing in prevalence. Surveillance of IPD to monitor changing serotype distribution and antimicrobial resistance is essential. [ABSTRACT FROM AUTHOR]

• Physical salt attack (PSA) is a key damage mechanism of concrete in salt-bearing environments. • The current paper presents a case study analyzing the condition of repaired concrete piles in 47-year-old administrative building. • Deterioration of the concrete piles was observed above the ground level and repair zones. • Thermal, mineralogical and microscopy analyses showed that the underlying mechanism of damage was PSA. • The repair concrete could not stop the progress of PSA on the concrete above it. • Recommendations for future repair strategies are made. Physical salt attack (PSA) is a key damage mechanism of concrete in salt-bearing environments. Multiple case studies were reported throughout literature on PSA of concrete; yet, without any case on the performance of repaired concrete elements. The current paper presents a case study analyzing the condition of repaired concrete piles in 47-year-old administrative building in Winnipeg, MB, Canada, after 22 years from repair works. Deterioration of the concrete piles was visually observed above the ground level and repair zones, in the form of scaling, crumbling and reduction of cross section. In addition to fluid transport and pore structural features tests, mineralogical, thermal and microscopy analyses were performed on concrete chunks/cores extracted from the piles to elucidate the underlying mechanisms of damage. The repair concrete was capable of mitigating chemical and physical sulfate attacks; however, it could not stop the progress of PSA on the concrete above it, urging for careful design of repair strategies for elements subjected to PSA. Recommendations for future repair in this case are also presented. [ABSTRACT FROM AUTHOR]

The objective of this study was to investigate the application of multi-temporal optical and polarimetric synthetic aperture radar (PolSAR) Earth observations for crop characterization. Crop dry biomass, Leaf Area Index (LAI), and Plant Water Content (PWC) were estimated and assessed using Machin learning approaches. An accurate estimation of crop parameters provides essential information to increased food production and plays a crucial role in the management of agricultural lands. Multispectral and PolSAR data provide valuable observations of spectral and structural properties which are essential for crops parameter modelling. The Earth observations used in this paper were collected by RapidEye satellites and Unmanned Aerial Vehicle Synthetic Aperture Radar (UAVSAR) system in the summer of 2012, over an agriculture area in Winnipeg, Manitoba, Canada. The RapidEye vegetation indices (VIs) and UAVSAR polarimetric parameters were used as inputs in artificial neural network (ANN) and support vector regression (SVR) models for canola biophysical parameters estimation. The best models were provided by SVR for canola. Also combining optical VIs and polarimetric features appeared as a powerful tool for crop parameters estimation in agricultural lands.

Influenza and Other Respiratory Viruses 10.1111/irv.12052 Background Outbreaks of influenza-like illness (ILI) are common in long-term care facilities (LTCFs) and result in significant morbidity and mortality among residents. Objectives We describe patterns of reported ILI outbreaks in LTCFs in Winnipeg, Canada, and examine LTCF and outbreak characteristics that influence the clinical outcomes of these outbreaks. Methods We analyzed the electronic records of all ILI outbreaks reported by LTCFs in Winnipeg from 2003 to 2011. Outbreak duration, ILI attack rates among staff and residents, and residents' death rates were calculated by presumed viral etiology, staff vaccination rates, type of influenza chemoprophylaxis used, and time to notification to public health. Results Of a total of 154 reported outbreaks, most ( N = 80) were attributed to influenza, and these outbreaks tended to have higher attack and death rates among LTCF residents compared with outbreaks caused by other respiratory viruses (12) or those of unknown etiology (62). About 92% of residents and 38% of staff of the average LTCFs were vaccinated. Chemoprophylaxis was used in 57·5% of influenza outbreaks. Regardless of presumed viral etiology, outbreaks reported within 3 days of onset ended sooner and had lower attack and mortality rates among residents. Conclusions Influenza-like illness outbreaks still occur among highly immunized LTCF residents, so in addition to vaccination of staff and residents, it is important to maintain competent infection control practices. Early identification and notification to public health authorities and possibly early initiation of control measures could improve clinical outcomes of ILI outbreaks. [ABSTRACT FROM AUTHOR]

This paper reviews the flood frequency characteristics of the Red River at Winnipeg. The impacts of persistence in the flood series on estimates of flood quantiles and their associated confidence intervals are examined. This is done by generating a large number of data sequences using a mixed noise model that preserves the short-term and long-term correlation structures of the observed flood series. The results reveal that persistence in the data series can lead to a slight increase in the expected flood magnitude for a given return period. More importantly, persistence is shown to dramatically increase the uncertainty associated with estimated flood quantiles. The 117-year flood series for the Red River at Winnipeg is demonstrated to be equivalent to roughly 45 years of independent data.Key words: flood frequency, extreme events, simulation, historical data.Cet article examine les caractéristiques de la fréquence des crues de la rivière Rouge à Winnipeg. Les impacts de la persistance dans la série de débits sur les estimés des quantiles de crues et leurs intervalles de confiance associés sont examinés. Ceci est effectué en générant un large nombre de séquences de données en utilisant un modèle avec bruits mixtes qui préserve la structure de corrélation à court et à long terme de la série de débits observés. Les résultats révèlent que la persistance dans la série de données peut mener à une légère augmentation de la magnitude anticipée de la crue pour une certaine période de retour. Plus important encore, il a été montré que la persistance augmente dramatiquement l'incertitude associée avec l'estimation des quantiles de crues. La série de 117 ans de débits pour la rivière Rouge à Winnipeg a démontrée être équivalente à 45 ans de données indépendantes.Mots clés : fréquence de crues, événements extrêmes, simulation, données historiques.[Traduit par la Rédaction] [ABSTRACT FROM AUTHOR]

The urgent cancer care (UCC) clinic at CancerCare Manitoba (CCMB) opened in 2013 to provide care to individuals diagnosed with cancer and serious blood disorders experiencing complications from the underlying disorder or its treatment. This study examined the impact of the UCC clinic on other health care utilization in Winnipeg, Manitoba, Canada. An interrupted time series study design was used to compare the rates of emergency department (ED) visits, primary care clinician (PCC) visits, and hospitalizations from 1 January 2010 to 31 December 2015. Rates of ED visits were also stratified by ED location, severity, and cancer type. We found a 6% (95% CI 1.00–1.13, p-value = 0.0389) increase in PCC visits, a 7% (95% CI 0.99–1.15, p-value = 0.0737) increase in hospitalizations, a 4% (95% CI 0.86–1.08, p-value = 0.5053) decrease in the rate of ED visits, and a 3% (95% CI 0.92–1.17, p-value = 0.5778) increase in the rate of ED visits during the UCC clinic hours after the UCC clinic opened. The implementation of the UCC clinic had minimal impact on health care utilization. Future work should examine the impact of the UCC clinic on other aspects of healthcare utilization (e.g., number of tests ordered and time spent waiting in CCMB's main clinics) and patient quality of life and patient and health care provider experience.

The use of fiber-reinforced composite materials for the construction and rehabilitation of civil engineering structures is relatively new. Structural members are routinely joined by bolted connections. Bolted connections are relatively easy to assemble and maintain, and are capable of transferring the high loads that typically occur in civil engineering structures. Currently there is a serious lack of knowledge on the behavior and design of bolted connections for fiber-reinforced composites. In light of this, a comprehensive experimental and analytical investigation was conducted at the University of Manitoba to study the behavior of bolted connections in composite materials appropriate for civil engineering applications. A total of 102 single-bolt connections were tested up to failure. The various parameters investigated were the width of the structural member, the edge distance, the thickness, and the direction of the fibers with respect to the applied load. The experimental program also included comprehensive material testing to determine the various in-plane material properties. This paper discusses the experimental program, test results, and various modes of failure as affected by the foregoing parameters. From the test results an analytical model and design procedure were developed as proposed in a companion paper. [ABSTRACT FROM AUTHOR]

High temperature superconducting (HTS) power cables are a potential solution for the grid integration of offshore wind farms since the HTS cable can conduct bulk wind power at low voltage levels. However, the transient current through the HTS cable in cases of low voltage ride through (LVRT) operation has a negative impact on the HTS cable operation due to the quenching phenomenon. This paper analyzes the impact of LVRT control strategies on the HTS cable operation. In addition, a coordinated control of wind turbines for LVRT improvement of an offshore wind farm is proposed. The feasibility of the HTS cable application for the grid connection of offshore wind farms is also discussed in this study. The proposed controller is designed for the wind turbine generator based on a type-4 permanent magnet synchronous generator. In the proposed controller, the transient current through the HTS cable is reduced by regulating the machine side power during fault conditions. The feasibility of the proposed controller is validated in the PSCAD/EMTDC program (Manitoba Hydro International Ltd., Winnipeg, Manitoba, Canada, version 4.2.1). The effects of transient current on the cable temperatures and resistances are analyzed in this study. Simulation results show that the proposed control strategy could reduce the transient current and temperature rise of the HTS cable. [ABSTRACT FROM AUTHOR]

This paper proposes a new control scheme for the low frequency AC transmission (LFAC) system aiming at extending the point-to-point configuration to form a multi-terminal electrical energy network. The multi-terminal low frequency ac (MT-LFAC) system configuration is based on the use of modular multilevel matrix converters (M3Cs) and virtual synchronous generator (VSG) control. The M3C is the next ac/ac converter generation, which is used as an interface with the conventional AC network and the LFAC electrical energy system. Application of VSG control is proposed to enable proper power sharing, to provide synchronization of each terminal, and frequency stabilization, thus, to offer multiterminal forming capability. Two different operation modes are applied in the system to damp the frequency deviation after a dynamic perturbation, which provides additional stabilization feature to the VSG. Frequency restoration mode and commanded mode of power sharing are applied as dynamic states to validate the robustness of the VSG control system. Besides, to solve the negative impact of low X/R ratio in the LFAC electrical energy system, we enhance the VSG control by proposing a virtual-impedance-based solution, which increases the output total impedance on the low frequency side and prevents the coupling between P and Q. The operation of the proposed system is examined by simulation results with a precise model of M3Cs in the PSCAD/ EMTDC software environment (version 4.2.1, Winnipeg, MB, Canada).

Drawing on qualitative data gathered in the inner city of Winnipeg, this paper seeks to answer the following questions: What do urban Aboriginals think of African refugees? Do Aboriginals feel threatened by the arrival of refugee migrants in their neighbourhoods? If so, why and if not, why not? Findings from this exploratory study reveal a mixed picture of how Native1 inner-city residents perceive newcomer refugees. Some Aboriginals have negative perceptions of refugees, largely caused by feelings of inter-group competition over jobs and subsidized housing. Other Aboriginals appear to have a sympathetic view of refugees, since they can identify with them as racialized minorities. [ABSTRACT FROM AUTHOR]

The housing difficulties facing many low income Canadians today is well documented. For newcomers, and particularly refugees, these challenges may be amplified. This paper considers the influence of legal status and place in the housing outcomes of government-assisted refugees and refugee claimants in Vancouver, BC and Winnipeg, MB. Results from the study indicate that while claimants in Vancouver face a more difficult 'pathway to permanent housing' than do government-assisted refugees, the same is not true in Winnipeg. More alarmingly, certain refugee groups face barriers beyond legal status and place, owing to characteristics of the group itself. [ABSTRACT FROM AUTHOR]

Abstract: An extensive research project is currently being carried out at the University of Manitoba, Canada, involving the development of glass fiber-reinforced polymer (GFRP) wind turbine towers. The towers consist of multi-cell segments, each segment constructed from eight filament wound cells jointed together with resin applied over their interface. The present paper mainly addresses the static and dynamic characteristics, such as failure static loads, modes of failure, fundamental frequencies and periods of such segmented composite towers. Both experimental and numerical results are presented. The experimental investigation involved the testing of two jointed scaled towers. These specimens had a total height of 4.88-m (16-ft) and were tested as cantilevers under static and dynamic loading. The testing was conducted at the W.R. McQuade Structural Engineering Laboratory of the University of Manitoba. Finally, finite element models were developed to analyze the structural behavior, static and dynamic, of single and multi-cell composite segments and towers. The results from the finite element models under static loading were validated through comparison with the experimental results. [Copyright &y& Elsevier]

Modern wide-bandgap (WBG) devices, such as silicon carbide (SiC) or gallium nitride (GaN) based devices, have emerged and been increasingly used in power electronics (PE) applications due to their superior switching feature. The power losses of these devices become the key of system efficiency improvement, especially for high-frequency applications. In this paper, a generalized behavioral model of a switch-diode cell (SDC) is proposed for power loss estimation in the electromagnetic transient simulation. The proposed model is developed based on the circuit level switching process analysis, which considers the effects of parasitics, the operating temperature, and the interaction of diode and switch. In addition, the transient waveforms of the SDC are simulated by the proposed model using dependent voltage and current sources with passive components. Besides, the approaches of obtaining model parameters from the datasheets are given and the modelling method is applicable to various semiconductors such Si insulated-gate bipolar transistor (IGBT), Si/SiC metal–oxide–semiconductor field-effect transistor (MOSFET), and GaN devices. Further, a multi-dimensional power loss table in a wide range of operating conditions can be obtained with fast speed and reasonable accuracy. The proposed approach is implemented in PSCAD/ Electromagnetic Transients including DC, EMTDC, (v4.6, Winnipeg, MB, Canada) and further verified by the hardware setups including different daughter boards for different devices.

South Korean immigration to Canada has increased since the East Asian economic crisis of the late 1990s. Korean immigrants in Winnipeg chose the city for many reasons: the introduction of the Provincial Nominee Program, structural changes in the home country, and individual family strategies to provide better educational opportunities for their children. This article examines how changes in the current wave of globalization, at both global and local scale, have affected the migration of Koreans to Winnipeg, Canada and how individual households chose their immigration destination. This study contributes to understanding of the less popular immigrant destinations of Canada using a multiscalar analysis that includes household level. In addition to economic purposes and children's education, changes of life style can be an important reason for immigrant location choice. Overall, the neoliberal economy in South Korea has pushed many Koreans to move to other countries, and the globalization of the Canadian economy has pulled nomadic middle-class members from other countries.

Background: research has reliably demonstrated cardioprotection from regular alcohol use. Heavy episodic drinking (HED), however, negates these beneficial effects and increases the risk of cardiovascular disease (CVD). The impact of age on the health effects of episodic drinking has not been evaluated. Objective: to examine the association between alcohol volume and pattern of consumption on the risk of cardiovascular morbidity and mortality across the lifespan. Design and Setting: prospective, community-based cohort study of adults in Winnipeg, Manitoba, Canada. Subjects: a total of 1,154 participants (580 men and 574 women) aged 18-64 surveyed at baseline (1990-91) on alcohol consumption levels and pattern of use. Methods: usual alcohol consumption was measured using a quantity-frequency approach. HED was estimated by asking participants how often they consumed eight or more drinks in one sitting in the past year. Questions were asked separately for wine, beer and spirits. Surveillance for cardiovascular events was conducted for 10 years (i.e. up to age 74 years). Diagnoses of CVD were obtained via health utilization records. Cox proportional hazard models were derived for both genders and for `young adults' (baseline age 18-34), `middle-aged adults' (baseline age 35-49) and `older adults' (baseline 50-64). Models were adjusted for marital status, cigarette smoking status and educational level. Results: Reduced risk of CVD was associated with usual consumption, whereas an increased risk was associated with RED. Among male usual drinkers, cardioprotection was afforded only to middle and older age groups. The benefits of regular consumption were seen only in the youngest age group among women. The heaviest usual consumption category was associated with a decreased risk of CVD in men. Heavy episodic drinking increased the risk of coronary heart disease in middle-aged men and was marginally significant in middle-aged women. Risk of hypertension was elevated in older men with heavy episodic drinking. Conclusions: The well-established relationship between regular alcohol consumption and decreased risk of CVD may not become evident until middle age or older in men. Women may benefit from usual consumption at a much younger age. In both sexes, however, these beneficial effects of alcohol use are negated when alcohol is consumed in a heavy episodic drinking pattern, particularly for middle-aged and older men.

The synchronous condenser (SC) has a broad application prospect in ultra-high-voltage direct current (UHVDC) systems. The SC's loss of excitation (LOE) is an important grid-related fault that may cause damage to the UHVDC. However, as the premise of the scientific protection configuration, knowledge of the SC's LOE feature and its impact on UHVDC is still missing. This article first analyzes the SC's LOE feature, offering a basic cognition of this fault. Secondly, the LOE SC's reactive power response to system voltage variation is studied in the single-machine infinite-bus system. This lends a foundation for transient UHVDC research. Finally, the LOE SC's impacts on steady and transient UHVDC are evaluated, respectively, considering different AC strengths and system faults through PSCAD/EMTDC (V4.6, Manitoba HVDC Research Center, Winnipeg, MB, Canada) simulations. The results show that: (1) LOE the SC absorbs reactive power while maintaining synchronous operation, its excitation current declines monotonically; (2) the LOE SC has an insignificant effect on steady-state UHVDC; (3) the LOE SC can restrain the overvoltage and benefit the rectifier's transient stability; and (4) to reduce the inverter's commutation failure, keeping LOE SC is more effective than separating it beforehand, while separating the LOE SC after the system voltage drop performs best. These conclusions could provide insights for the protection's criterion and operation mode selections. [ABSTRACT FROM AUTHOR]
